GFB Valves are well suited to the Audi/ Volkswagen 1.8T engine both transverse and longitudinal. They are available for TT, A4, A3, Golf GTI and Passat. The spring rate has been specifically designed for the 1.8T engine. 

FOUR REASONS:

1 - Driveability
2 - Fuel Efficiency
3 - Boosting Up Applications (Factory valves can leak like a sieve!)
4 - The Noise!

They're engineered to produce peak performance under ALL conditions. A blow-off valve comes into play when the throttle is closed suddenly under boost conditions. A poor quality component actually slows acceleration and can cause "compression stall" … causing you to stall at the lights.

But that's the least of your problems. Imagine your turbocharger spinning at 80,000rpm pumping a truckload of air through your inlet pipes at nearly 90 metres per second … then you suddenly close the throttle. The "reverse thrust" forces produced are so huge, you can end up with a damaged turbocharger!

GO FAST BITS Hybrid blow-off valves overcome the problem by venting most of the non-required intake pressure into the atmosphere, while a small portion is vented back to the turbo and airflow meter-enough to stop problems such as excessive fuel use, backfiring and engine shudder at half acceleration (experienced with purely venting-to-atmosphere valves).

The majority of factory-installed blow-off valves vent ALL the air back into the inlet pipes, usually after the air flow meter. That also means the pressurised air is returned to the turbocharger in a HOT condition … and hot air produces poor power!

COOL OPERATION - MORE POWER ...

Because GO FAST BITS blow-off valves are engineered to vent out hot air, they produce a continuous cooler charge from the turbo. GFB blow-off valves ...
